You guys are thinking in terms of still photos. In that case I spread my pictures on more than one card but for video a larger faster card is a good thing. These cards start at about $300USD I believe.

UDMA 6 is just the speed rating. I want my UDMA cards to go up to 11 ;^)

Even if it didn't help with the shooting, I'd really appericiate the faster copy speeds if I had 64gb of data to move to the computer (USB 3.0\ Firewire 1600 anybody?) 64GB transfers can be a bit painful on my current setup.

Here's some video of my friend Chase Jarvis shooting with a D3X and the new UDMA 6 card. Pay attention to the night shots he takes with flash, crazy cool stuff! That's me on the scooter thingy at the end.

Niko - IMHO the new sandisk is priced very fair - if someone is living off the camera, than spending $800 shouldn't be a problem, as for me 64GB is a lot of photos - around 4000-4500 raw+jpgs, enough for a week trip; would I buy the 64gb version, no - would prefere to get 4 16gb as this brings the reliability to higher level, and brings down the potential risk of loosing data - and I really would love to see 4 and 8gb cards - as You can put them on a DVD without any hassle

as for kingston, it's cheap - and thats a big pro, but the con is the speed, it's sooo slow when You shoot continuous raw, apr. it needs 3-4 more time to save camera buffer than sandisk extreme III (same for sd and cf)
